Why a BSD license and not GPL?
The UDI environment is coupled rather tightly to the OS kernel. Because it may need to use some undocumented OS interfaces, the UDI environment could reasonably be considered a derived work of the kernel and vice versa. We chose the BSD license to allow free distribution while avoiding the controversy of “derived works” in GPL. We do intend for the reference implementation to be an active free software project. If the BSD vs. GPL thing becomes a sticking point, we, the copyright holders can fix that.
